Diary: The Alert That Fired on Tuesday
Diary entry: Prenetics landed on Trend Watch on Monday, a Hot Prospects alert fired on Tuesday at $22.97, and the stock was 16.6% higher by the next Monday.
This entry is about the one feature I'd keep if everything else went away: alerts. Nobody actually reads screeners every day, and with an alert running you don't have to.
Monday: the setup
On Monday, August 24, Prenetics (PRE) appeared on the Trend Watch list at $20.20. The readings were unusually strong: overall 88% Buy, medium-term 100% Buy. I didn't buy anything and I didn't sit watching the chart. I just added PRE to my watchlist, where my standing stock alert covers it. That alert runs on the Hot Prospects screener, checks every 5 minutes inside a fixed afternoon window, and only notifies on newly matching tickers. It stays quiet until something changes.
Tuesday: one email
Tuesday afternoon the email came in: PRE had entered Hot Prospects at $22.97. The trend list had the name first, the momentum list picked it up a day later, and the alert told me without me checking anything. It was one email with one name, because the alert never repeats a ticker it already reported.
I gave it my usual five minutes: the chart, then the AI chat, where I asked what volume had done over the past week and whether any news explained the jump. Then back to work.
The rest of the week, one row per session
| Date | Event | Price | Change vs alert |
|---|---|---|---|
| Mon Aug 24 | On Trend Watch (88% Buy) | $20.20 | -12.1% before the alert |
| Tue Aug 25 | Alert: entered Hot Prospects | $22.97 | 0.0% |
| Wed Aug 26 | Still listed | $23.25 | +1.2% |
| Thu Aug 27 | Still listed | $25.78 | +12.2% |
| Fri Aug 28 | Fourth consecutive session on the list | $26.25 | +14.3% |
| Mon Aug 31 | Where it stands as this entry is written | $26.35 | +16.6% |
Measured from the Monday Trend Watch listing instead of the Tuesday alert, the same week is +30.4%. The gap between the two dates is worth a look. The Monday listing came earlier, before the second list agreed, so it carried more uncertainty and showed the bigger move. The Tuesday alert came after both lists agreed and still showed 16.6% over four trading days. Neither is the right answer. The platform shows both timestamps, so you can weigh that trade-off yourself.
The honest footnote
Picked after the fact, as always in this series. Most alert emails end in a shrug, not a week like this, and a stock that rises four sessions in a row can just as easily fall four in a row. The workflow itself is what I can count on: the lists cover 8,400 symbols, the alert watches the lists, and I read one email.
